Specification of'Lettrs Patent. Patented J 11119 24, 1919 Application filed March 18, 1919. Serial No. 283,332.

Kansas City, in the county of, Wyandotte and State of Kansas, have invented a certain new and useful Improvement in Combination-Padlocks, of which the following is a specification.

My invention relates to improvements 1n combination padloeks.

The object of my invention is to provide a combination padlock which is simple in which is strong and durable and not liable to get out of order, which permitsof a quick and easy change in the combinatlon, which affords a maximum of efficiency and secures it from unauthorized tampering, and which may be quickly unlocked by a person acquainted with the combination.

A further object of my invention -1S provision of novel means for holding tumblers in the proper position when hasp is withdrawn.

The novel features of my inventlon hereinafter fully described and claimed.

In the accompanying drawings whlch illustrate the preferred embodiment of my invention,

Figure 1 is a side elevatlon of my 111 proved padlock, shown in the locked position.

Fig. 2 is a horizontal sectional view on the line 2-2 of Fig. 8. Fig. 3 is a perspective vlew of the tumbler locking lever. v Fig. 4 is a cross section on the line 44 of Fig. 5.

Fig. 5 vertical section and partly in s1de elevatlon of the padlock in the locked position.

Fig. 6 is a bottom view of the padlock; Fig. 7 is a side elevation, partly-broken away, of the hasp.

Fig. 8 is a side elevation of the casing, the two members of which are shown in the open position.

Fig. 9 is a horizontal sectional view on the line 9-9 of Fig. 5.

Similar reference characters deslgnate similar parts in the different views.

1 designates a hasp which is of inverted U-shape of the ordinary type and. whlch 1s the the the is a central view shown partly in provided on the inner side of each'of its arms with notches 2 respectively adapted to receive horizontally disposed tumblers 3 winch are mounted one above the other on a vertical support comprising a vertical pin 4 and a vertical stem 5 disposed in alinement one above the other, the pin 4 being rigidly secured at its upper end in a horizontal top member 6 of one of the members 7 of the casing which is hinged by a vertical pintle 8 to the other casing member 9, as is best shown in Figs. 2 and 8.

The stem 5 is rotatably mounted in the bottom member 10 of the casing member 7.

' The stem 5 extends upwardly from a horizontal disk 11 which is provided with a circular row of graduations 12 which are adapted to register with an indicating mark 13 on the under side of the bottom member 10, as is shown in Fig. 6. The disk 11 is;

turned by means of a central downwardly extending thumb piece 14.

Referring particularly to Fig. 5, it will benoted that the three uppermost tumblers 3 are rotatably mounted on the pin 4, and. the lowermost tumbler 3 is rigidly secured to the stem 5.

'The tumblers 3 are spaced apart from each other by collars l5 rigidly attached to the pin 4. The lowermost tumbler 3 has mounted in it an upwardly extending pin 16, which is adapted to be removably mounted in any one of an annular row of vertical holes 17 arranged concentrically around the stem 5, each of the other tumblers 3 is provided with a similar circular row of holes 17 in the manner illustrated in Fig. 4.

' A vertical pin 18 is mounted in one of the holes 17 of thetumbler 3 next above the lowermost tumbler, as shown in Fig. 8. The pin 18 extends downwardly in the path of the pin 16 and upwardly in the path of a in 19, which is mounted in one of the holes 17 of the tumbler next above. The pin 19 extends upwardly into the path of a pin 20, which is mounted in one of the holes 17 in the uppermost tumbler 3 and which projects downwardly therefrom, as shown in Figs. 5 and 8.

By adjusting the pins 16, 18, 19 and 20 in different positions in holes 17,.the combina tion may be changed at will. Each tumbler 3 is provided on its periphery with two diametrically opposite-notches2l adapted .to respectively receive the arms of the hasp 1, in the. mannershown in Fig. ft.

The casing. member 9 is provided with two vertical holes 22 adapted to. have inserted therein the two arms of the hasp 1.

The top member 6 is provided with two verso the two hinged members 7 and 9 will beheld by the hjasp in. the lowest position."

When the casing member;9 is swung to the closed position shown in Figs, 1, 4, 5 and 9, the holes 22 and23 andrecesses 24 will be in vertical alinement, so as to admit the arms of'the haspl, when thetu-mblers3 are all turnedto a position in which the notches 21 will be disposed in two vertical rows. At such time, the hasp 1 may beinserted into or removed from the casing. To hold the tumblers 3- in this position, and to prevent their accidental displacement therefrom, while the haspzis outof'the casing, I provide the following described releasable locking mechanism:

A U-shaped lever 25, Fig. 3, has its horizontal arms respectively provided avithholes 26 and 27', th=rough which respectively extendtwo vertical pins--28 and'29, Fig. 8,

mounted respectively in the top member 6 and the bottom member 10 of the casing member 7'. The vertical portion whichconnects the arms of the lever-25 is normally forced"inwardly bya suitable spring 30, Fig.9, and Fig. 2, so as to enter notches 31, two of which are provided in the periphery ofeaclr tumbler 3 in diametrically opposite positions, as shown ii -Fig. 4. l/Vhen one setof notches; 31=is in a-linement with and adapted i to receive the vertical part of the lever 25, the-notches 21 will be-di sposecl so ,as to receive the arms of the hasp '1;

In order that the lever: 25 may be disen gagedfi'oni the tumla'lers 3*, when the hasp 1:

is inserted in the lockedpositionshownin Fig. 5, the lower armof-the lever 25' is pro-- videdwith a. lateral eXtens1on-32, which 1s beveled on' its upper-- SlfilG' andi which is adapted to be struck by thelower I end o-t one of the arms of the hasp l and moved later ally thereby-a distance-sufficient to swing the level 25 out of the adj acent notches3l, as shown'in Figs. 4 andi)! The member 9 is held releasablyin the closed; position shownin Figs. 1, 4, 5' anda9, when the-hasp 1' is removedfrom the casin b means-oftwo horizontal screws 33 shown in Figs. 1

and 9.. By removing the screws 33 and the hasp 1. the casing member 9 may be swung to, the openposition. By then removinga pin 34- which attaches the lowermost tumbler 3'to the stem 5, and by removingdpins 35 which attach the three lowermost collars 15 .to the pin 1, the tumblers 3 may be removedandthe pins 16, 18, 19 and 20 may then be mounted in the holes 17 such as will effect the required. new combination. The removed parts may then be replaced in operative position, with the notches 21 in alinement'with the holes 23, after whichthe casing member 9 is swung to the closed position and reattached by the screws 33 to the so casingmember 7. At this. time, thelever 25' will enterthe adjacent notches. 31 of the tumblers 3, thereby holding the tumblers from movement until the haspliisiinsertedi in the closed position shown in. Eig. 5;

To look the hasp in the closed5position, the disk.'11 is turned by meansofithe thumb piece 14, thereby turning the-lowermost 1111111- bler 3 through theinteri'l'iediacy of the stem 5. By continued turning of the itlnnnb piece- 1%, the pin l6 will engage and carry with itth'e pin 18 and thetumbler attached thereto. The pin 18', upon continued:zturningof the finger piece llwill engageandcarry with it the pin19, whiclriu/turnwill engage and carry with itthe pin .20.. By means of such turning of thesthumb piece 14, the tumblers 3 may bebrought to positions in. which atleast some of-themiwill enteimthe, notches 2 of the hasp 1,=thus.locking theJOO hasp in-the casing. members 9 and '7.

To unlock the padlock,v therthumbpiece 14 v is turned continuously in i one direction, forthreeor more turns and to aiposition in i which the indie. ting mark 13 will registen with the firstigraduatiouqof the combination. at which time the uppermosttumbler 3 will be in the unlocking position, that is witl its notches21 in register with thel holes 23. The thumb piece 1i is. then turned in the reverse direction two revolutions and to the second number of the combination This sets the second tumbler from the top, in the unlocking position. The thumbspiece 14E- iszthen turned in theoppositedirection one turn and to the next nu-mbenof-the; combination. This will set the; third tumbler from-the top in, the unlocking position. The thumb 1 piece. 14 is reversed in: rotation -;to the fourth number of the combination, All the; tumblers will now. be in the unlocking position. with their notches 2l.inalineme nt. with the holes 23, and the hasp,.can ,'be r e.-, moved from the casing. When thisghasbeen done, the spring 30 will .fOTQG';l3l;1Q lever -@255 into the adjacent-notches 31 of the tumblers, thus locking the latter; from ,accidentalgdis placement, from the unlocking position,

Each "of the tumb1ers-31is provided with two oppositely disposed peripheral notches 31 in order that the locking lever 25 may enter one of the notches irrespective of the relative arrangement of the pins 16, 18, 19 and 20 in the holes 17.
